When a background copy of a cg is written we complete any work associated
with that bmsafemap. If new work has been added to the non-background
copy of the buffer it will be completed before the next write happens.
The solution is to do the rollbacks when we make the copy so only those
dependencies that were present at the time of writing will be completed
when the background write completes. This would've resulted in various
bitmap related corruptions and panics. It also would've expired journal
entries early causing journal replay to miss some records.

The sample rate control stats would show impossibly large numbers for
"successful packets transmitted." The number was a tad under 2^^64-1.
So after a bit of digging, I found that the sample rate control code
was making 'tries' turn into a negative number.. and this was because
ts_longretry was too small.
The hardware returns "ts_longretry" at the current rate selection,
not overall for that TX descriptor. So if you setup four TX rate
scenarios and the second one works, ts_longretry is only set for
the number of attempts at that second rate scenario. The FreeBSD HAL
code does the correction in ath_hal_proctxdesc() - however, this isn't
possible with EDMA.
EDMA TX completion is done separate from the original TX descriptor.
So the real solution is to split out "find ts_rate and ts_longretry"
from "complete TX descriptor". Until that's done, put a hack in
the EDMA TX path that uses the rate scenario information in the ath_buf.

in nve(4). The OS_API structure defined in os.h expects NV_API_CALL
attributes, effectively regparm(0), on its function pointers, but all
the functions were declared and defined without this attribute.

- Do not try to steal load from other CPUs if there was no contest switches
on this CPU (i.e. it was idle all the time and woke up just for bus mastering
or TLB shutdown). If current CPU was idle, then it is quite unlikely that some
other CPU has load to steal. Under high I/O rate, when TLB shutdowns cause
numerous CPU wakeups, on 24-CPU system load stealing code may consume up to
25% of all CPU time without giving any benefits.
- Change code that implements spinning for load to restart spin in case of
context switch. Previous code periodically called cpu_idle() even under
high interrupt/context switch rate.
- Rise spinning threshold to 10KHz, where it gives at least some effect
that may worth consumed power.

small address space systems.
VM_MAX_AUTOTUNE_MAXUSERS - the max maxusers that will be autotuned based on

VM_MAX_AUTOTUNE_NMBCLUSTERS - max nmbclusters based on physical memory.
These are set to the old values on i386 to preserve the clamping that was
being done to all arches.
Another macro VM_AUTOTUNE_NMBCLUSTERS is provided to allow an override
for the calculation on a MD basis. Currently no arch defines this.

This is primarily for the TX EDMA and TX EDMA completion. I haven't yet
tied it into the EDMA RX path or the legacy TX/RX path.
Things that I don't quite like:
* Make the pointer type 'void' in ath_softc and have if_ath_alq*()
return a malloc'ed buffer. That would remove the need to include
if_ath_alq.h in if_athvar.h.
* The sysctl setup needs to be cleaned up.
I'm using this to debug EDMA TX and RX descriptors and it's really helpful
to have a non-printf() way to decode frames.
I won't link this into the build until I've tidied it up a little more.
This will eventually be behind ATH_DEBUG_ALQ.

as threads transition from realtime to timeshare. The latency is

latency becomes (nthreads - 1) * min_slice.
